The electricity market in Great Britain is entirely privatized and liberalised, meaning that there is full competition between private companies. The electricity industry consists of three main parts: 1) Generation (making electricity); 2) Networks (transporting it from where it is generated to where it is used); 3) Supply (selling it to the end consumer)

ELEXON monitors and responds to industry-wide consultations that may have an impact on the provisions in the BSC, on ELEXON, or on our customers. We also publish consultations on proposed changes to our processes.

ELEXON compares how much electricity generators and suppliers say they will produce or consume with actual volumes. We work out a price for the difference and transfer funds. This involves taking 1.25 million meter readings every day.

The BSC Change process is used to progress changes to the BSC arrangements in response to any concerns, problems or defects that Parties may identify in the current processes. Under these processes, changes can be made to the Balancing and Settlement Code, its Code Subsidiary Documents and to BSC Systems.

A CP is a detailed proposal which is raised in order to amend CSDs and/or BSC Systems, but would not alter the BSC. A CP must have a clear aim, a single defined solution and contain the relevant redlined documentation changes.

The Releases process is part of the BSC change procedure and includes information about where changes are being introduced, how they impact on certain areas of the industry and whether your systems will need to undergo tests to ensure they are up-to-date and meet required standards.

This page lists all Consultations relating to Operations and Settlement. The consultations allow ELEXON to gather feedback from the industry about proposed changes so that any concerns are considered as part of our processes.

Contract notifications, bids and offers, and other data, is sent to BSC Central Services for Imbalance Settlement. At the end of a Settlement Period, BSC Systems compare a Party’s contracted (traded) volume with the metered volume of energy used in the Settlement Period. If a Party is in imbalance of its contracted volume, then itMore…

Balancing Mechanism (BM) Units are used as units of trade within the Balancing Mechanism. Each BM Unit accounts for a collection of plant and/or apparatus, and is considered the smallest grouping that can be independently controlled.

Market Domain Data is the central repository of reference data used by Suppliers, Supplier Agents and Licensed Distribution System Operators (LDSOs) in the retail electricity market. It is essential to the operation of Supplier Volume Allocation (SVA) Trading Arrangements.

Metering Systems accurately record the flow of electricity to (an Import) or from (an Export) a site. ELEXON uses Metering System data to calculate energy imbalance charges. These charges are applied to BSC Parties who use more or less energy than they have contracted to buy or generate.

This section lists all the areas on the BSC website and supporting websites where you can access data. You can also see the various monthly reports that we produce, which are based on the large amounts of data we generate.

This page includes information on the process of entering the electricity market. It will also tell you all about the different ways that we monitor and manage your performance against your requirements and obligations within the Balancing and Settlement Code (BSC).

Part of ELEXON’s role as administrator of the BSC is to monitor the compliance of all BSC parties and to run Performance Assurance activities. There are a number of techniques that ELEXON uses to confirm compliance or identify issues that may need to be addressed.
